Hello Christophe,

Thank you again for responding to my message.

I see now, a MLine is used for the 1D case and a MEdge is used in the 2D
case.So since I am dealing exclusively with 2D meshes, would I really need
the MLine class? Or will there be cases when a 2D mesh uses the MLine class?

I believe that I asked this in my previous message, but I will ask it again

could you go a little bit more into detail of what you mean by "This will
not expose any of the internal complexity of the code."?
